翠碧一号不同外观特征烟叶内在质量分析

Study on Internal Quality of CB-1 Tobacco Leaves with Different Appearance Characteristics

为进一步探究不同外观特征对特色烤烟品种翠碧一号(CB-1)烟叶质量的影响,以中部烟叶为试材,研究了橘黄(C2F、C3F)、不同挂灰面积(10%、20%、30%)、不同光滑面积(10%、20%、30%)和不同含青程度(C3V、GY1)等4种外观特征类型烟叶的外观和内在质量。结果表明,外观质量总体表现为橘黄>挂灰>含青>光滑,随着外观特征面积比例增加,挂灰、光滑和含青烟叶外观质量均显著降低;各处理主要化学成分均在适宜范围内,随着挂灰面积比例增加,还原糖和总糖含量、糖碱比逐渐降低,光滑烟叶表现出明显的高糖低碱,糖碱比均显著高于其他处理;C2F烟叶感官评吸质量最优,10%和20%挂灰、10%光滑及C3V烟叶的感官评吸质量与C3F烟叶相当,10%光滑和C3V烟叶清甜香风格最为彰显,但蜜甜香明显减弱。聚类结果显示,10%和20%挂灰烟叶感官评吸品质及风格特征最接近C3F,其次为10%光滑和C3V烟叶;高挂灰程度(30%)、高含青程度(GY1)、中高光滑程度(20%、30%)的烟叶工业可用性显著降低。总之,在实际分级验级中,CB-1品种C3F等级烟叶可放宽挂灰面积至20%、含青程度至微浮青面积10%,应严格限制光滑面积在10%以内。

In order to further explore the effects of different appearance characteristics on the quality of tobacco leaves of CB-1,the cutters were used as experimental materials to study the appearance and internal quality of orange(C2F,C3F),different scalding degree(10%,20%,30%),different slick degree(10%,20%,30%)and different green degree(C3V,GY1).The results showed that the overall appearance quality was orange>scalding>green>slick.With the increase of the proportion of appearance characteristic area,the appearance quality of scalding,slick and green tobacco leaves decreased significantly.The main chemical components of all treatments were in the suitable range.With the increase of scalding degree,the contents of reducing sugar,total sugar and the ratio of sugar to alkali decreased gradually.Slick tobacco leaves showed obvious high sugar and low alkali,and the ratio of sugar to alkali was significantly higher than that of the other treatments.The sensory quality of C2F tobacco leaves was the best,and the sensory quality of 10%and 20%scalding,10%slick and C3V tobacco leaves was the same as that of C3F tobacco leaves.While the sweet-scented style characteristics of 10%slick and C3V tobacco leaves were more obvious,the honey-sweet style characteristics were weakened.The results of cluster analysis showed that the sensory quality and style characteristics of 10%and 20%scalding tobacco leaves were the most similar to C3F,followed by 10%slick and C3V tobacco leaves,and the industrial availability of tobacco leaves with high scalding degree(30%),high green degree(GY1)and medium and high slick degree(20%,30%)decreased significantly.In short,in the actual grading of CB-1 varieties,the saclding and green degree of C3F can be relaxed to"20%scalding area","10%slightly green area"respectively,and the slick area should be strictly limited to less than 10%.
